The health profile for people with serious mental illness is pretty grim. In general, they have a lower life expectancy — 25 years less than the general population — which is largely due to cardiovascular disease related to high rates of obesity and smoking.
But a new study by researchers at Massachusetts General Hospital found that after one year, seriously mentally ill patients who quit smoking — even though they gained about 10 pounds — had a lower risk of developing heart disease compared to those who didn’t quit. That’s the good news part of the research, published online in The Journal of Clinical Psychiatry. The bad news is that if those people — who already have high rates of obesity — continue to gain weight, it’s fairly likely they will develop a slew of other health problems, including cardiovascular disease, said the study’s lead author, Dr. Anne Thorndike, an assistant professor at MGH and Harvard Medical School.
“Quitting smoking is the single most important behavior change that anyone, [including] people with serious mental illness, can do to reduce their risk of developing cardiovascular disease,” Thorndike said in an interview. “But the weight gain is a red flag. The story’s not over at one year … If they continue to gain weight, all the health factors will worsen and contribute to higher rates of cardiovascular disease.”
